A one size fits all database doesn't fit anyone

All Things Distributed

A common question that I get is why do we offer so many database products? To do this, they need to be able to use multiple databases and data models within the same application. Seldom can one database fit the needs of multiple distinct use cases. The days of the one-size-fits-all monolithic database are behind us, and developers are now building highly distributed applications using a multitude of purpose-built databases. Purpose-built databases.

Should You Use ClickHouse as a Main Operational Database?


What if we use ClickHouse (which is a columnar analytical database) as our main datastore? Well, typically, an analytical database is not a replacement for a transactional or key/value datastore. how many messages was send for some time period and how much it cost) and a typical key/value queries like: “return 1 message by the message id” Using a columnar analytical database can be a big challenge here. At the same time, it was not originally designed that way.

MySQL High Availability Framework Explained – Part II: Semisynchronous Replication


MySQL semisynchronous replication, by design, can fall back to asynchronous mode based on the slave acknowledgement timeout settings or based on the number of semisynchronous-capable slaves available at any point in time. The default design of the ScaleGrid HA framework is to avoid falling back to asynchronous mode. This is a conscious design decision we have made as the default behavior which is, of course, configurable based on the application requirements.
